Bullous Impetigo – Causes, Symptoms, Treatment, and Prevention

Bullous impetigo is a contagious skin infection caused by the bacteria Staphylococcus aureus or Streptococcus pyogenes. It is characterized by the formation of fluid-filled blisters that quickly develop into large, crusty sores. This condition mainly affects children aged 2 to 5 years, but it can also occur in adults.

The bacteria responsible for bullous impetigo can enter the body through a cut, scratch, or insect bite. Once inside, they multiply and release toxins that cause the skin to blister. These blisters are often painless but may be itchy and prone to rupture, leading to the formation of yellow or honey-colored crusts.

If left untreated, bullous impetigo can spread to other parts of the body or to other individuals through direct contact. It is important to seek medical attention if you suspect you or your child has this infection. A healthcare professional can diagnose bullous impetigo based on its characteristic appearance and may prescribe antibiotics to treat the underlying bacterial infection.

What is Bullous Impetigo?

Bullous impetigo is a contagious bacterial infection that primarily affects infants and young children. It is characterized by the formation of large, fluid-filled blisters on the skin. These blisters, also known as bullae, are often found in areas such as the face, arms, legs, and diaper area.

Caused by certain strains of bacteria, particularly Staphylococcus aureus, bullous impetigo spreads easily through direct contact with an infected person or by touching contaminated objects. The bacteria enter the body through small breaks in the skin, such as insect bites, cuts, or scratches.

Signs and Symptoms

Bullous impetigo typically starts as a cluster of tiny blisters that quickly grow in size and become filled with fluid. The blisters are usually painless but may be itchy. After a few days, the bullae burst, leaving behind a raw, moist or crusty area of skin. The affected areas may be red and swollen, and in some cases, there may be a honey-colored crust.
